CMR Series
Crydoms CMR Series Solid State Relays were developed to offer the advantages of semiconductor switching technology in a
compact, self contained package. Quick and easy installation is coupled with low drive power requirements and efficient,
reliable power SCR output. Box Clamp terminals and LED status indication complete the package. This compact new design
offers up to 65Arms in ambient temperatures of 25°C.
Manufactured in Crydom’s ISO 9001 Certified facility for optimum product performance and reliability.
APPROVALS: UL, CSA, VDE, CE Mark.
MOUNTING OF CMR SERIES OF SOLID STATE RELAYS
CMR Series SSRs are designed to fit to an industry standard TS35 DIN Rail. Mounting clip incorporates tabs for screw mounting to panel.
MOUNTING TO THE DIN RAIL
Locate rail and align with non moveable
end of CMR DIN clip Using reasonable
force, push CMR in the direction of the
arrow shown.
REMOVAL FROM DIN RAIL
Pull release tag in direction of arrow using
blade of screwdriver.
MOUNTING CONSIDERATIONS
To achieve maximum ratings, there must be
a minimum spacing of 1.6 inch (40mm)
between the devices in free air.

THERMAL CONSIDERATIONS
The CMR power switching range is based on semiconductor
technology and therefore generates heat during operation.
The following deating curves must be observed before installation.
Crydom products are rated for 100% Duty Cycle.
